|The calibration of the anemometers is performed in a wind tunnel, by direct comparison with a reference.
The reference device used by the laboratory over the whole
velocity range is a laser-Doppler anemometer (L.D.A.)
The minimum COFRAC calibration programme includes 5 velocity values repeated once, i.e. 10 measuring points.
